BACKGROUND

Currently high-end mobile devices such as smartphones and tablet computers provide abundant storage for storing applications, media files and documents, etc., by providing the respective devices with high-capacity memories or by providing the respective devices with a connection to cloud-based storages.

Further, users often use cameras included in the mobile devices to take photos and/or videos, and also store a large volume of such photos and/or videos in their mobile devices and/or the cloud-based storages. Also, the users often download various files such as, for example, media files and documents from other devices such as, for example, servers or other mobile devices, and store the downloaded files in their mobile devices and/or the cloud-based storages.

Some users manage their content files using a conventional file managing scheme such as, for example, folder classification and/or keyword-based tagging. However, such a conventional file managing scheme requires extra efforts of the users, in that the users should store data in suitable folders and/or add suitable keywords and tags in advance. Furthermore, even with the file managing scheme, it is still difficult for the users to easily find and select the desired files from storage in which a large number of files are stored.

SUMMARY

In an example, a method performed under control of an electronic device may include: gathering first information on or from one or more devices nearby the electronic device in response to a content file creation event on the electronic device; gathering second information on or from one or more devices nearby the electronic device in response to a content list creation event on the electronic device; calculating a similarity between the first information and the second information; and generating a content list based at least in part on the similarity between the first information and the second information.

In an example, a method performed under control of an electronic device may include: detecting a content file creation event; gathering information on or from one or more devices nearby the electronic device; and storing a content file with the information on or from the one or more nearby devices as metadata corresponding to the created content file.

In an example, a method performed under control of an electronic device may include: detecting a content list creation event; gathering information on or from one or more devices nearby the electronic device; calculating one or more similarities between the information on or from the one or more nearby devices and metadata corresponding to one or more content files stored in a storage; and generating a content list based at least in part on the calculated one or more similarities.

In an example, an electronic device may include: a nearby device information gathering unit configured to obtain information regarding one or more devices nearby the electronic device; a content ranking unit configured to determine relevance of one or more content files stored in a storage based at least in part on the information regarding the one or more nearby devices when a content list creation event is triggered; and a content list presenting unit configured to present a content list in order of the relevance determined by the content ranking unit when the content list creation event is triggered.

In an example, a computer-readable storage medium may store a program for causing an electronic device to present a content list, the program including: a nearby device information gathering module configured to obtain information regarding one or more devices nearby the electronic device; and a content ranking module configured to determine relevance of one or more content files stored in the electronic device based at least in part on the information regarding one or more nearby devices when a content list creation event is triggered.

DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the Figures, can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are explicitly contemplated herein.

This disclosure is generally drawn, inter alia, to methods, apparatus, systems, devices, and computer program products related to a context-based content list generation scheme.

Technologies are generally described for generating a list of content files such as, for example, a list of photos, videos or documents in an electronic device such as, for example, a smartphone and a tablet computer. In some examples, the electronic device may generate the list of the content files in order of similarities or relevancies between a context at the time of generating the content files and a context at the time of generating the list of the content files. In some examples, the electronic device may determine the display order of the list of the content files by considering where the electronic device is located, which devices are located near the electronic device, and so on, both at the time of generating the content files and at the time of generating the list of the content files.

In some examples, when a content file creation event is triggered on the electronic device, the electronic device may gather first information on or from one or more devices nearby the electronic device (e.g., Wi-Fi and/or Bluetooth MAC addresses of the nearby devices), and store a content file with the first information as metadata corresponding to the created content file. Then, when a content list creation event is triggered on the electronic device, the electronic device may gather second information on or from one or more devices nearby the electronic device (e.g., Wi-Fi and/or Bluetooth MAC addresses of the nearby devices). Then, the electronic device may calculate similarities between the first information and the second information, and generate the list of the content files based at least in part on the similarity between the first information and the second information.

In some examples, the content file creation event and the content list creation event are respectively triggered by an input from a user of the electronic device. In some examples, the content file creation event may be triggered when the user captures a photo with a camera in the electronic device, and the content list creation event may be triggered when the user activates a photo viewing application or a photo editing application in the electronic device. In other examples, the content file creation event may be triggered when the user captures a video with a camera in the electronic device, and the content list creation event may be triggered when the user activates a video playing application or a video editor application in the electronic device. In still further examples, the content file creation event may be triggered when the user receives or tries to receive a file from other devices, and the content list creation event may be triggered when the user activates an editor or a viewer for the received file.

In some examples, the electronic device may identify one or more nearby devices in the vicinity of the electronic device by detecting Wi-Fi and/or Bluetooth MAC addresses of the nearby devices, both at the time when the user creates or stores content files (e.g., photos, videos or documents) and at the time when the user tries to browse the content files, and generate or display the list of the content files in order of similarities in the nearby devices. Accordingly, the user can immediately select a desired content file among multiple content files without the extra effort such as adding tags, classifying folders, and/or managing filenames, etc.

By way of example, but not limitation, a user of an electronic device, such as a smartphone, may store materials distributed in college classes in his/her smartphone, take photos with his/her family and/or friends and store the photos in his/her smartphone and/or a cloud-based storage, and save document files distributed at his/her office in his/her smartphone and/or the cloud-based storage. When the user activates a photo viewing application or a photo editing application on his/her smartphone at home, the smartphone may detect smartphones of other users located in the vicinity of the user (e.g., family members), gather information such as, for example, MAC addresses of the smartphones of the family members, and may display photos taken with the family members and/or a list thereof preferentially.

When friends of the user are visiting the user and are located closer to the user than the family members are, the user's smartphone may detect smartphones of the friends, and gather information such as, for example, MAC addresses of the smartphones of the friends. In such cases, when the user activates the photo viewing application or the photo editing application, the smartphone of the user may display a content list in which photos with the friends (who are located closer to the user than the family members) are ranked first and photos with family members are ranked second.

When the user activates a file viewer or editor on his/her smartphone in a classroom or office setting, the smartphone of the user may detect MAC addresses of smartphones of other users located in the vicinity of the user (e.g., classmates and/or workplace colleagues), and display a list of materials for the class or meeting preferentially, while in cases where the user activates the file viewer or editor on his/her smartphone in another classroom or meeting setting, the smartphone of the user may detect MAC addresses of smartphones of other users located in the vicinity of the user (e.g., classmates and/or colleagues), and, display a list of materials for the other class or meeting preferentially.

FIG. 1 schematically shows an illustrative example of an environment where an electronic device may create and store a content file, arranged in accordance with at least some embodiments described herein.

As depicted, when a content file creation event 100 is triggered in an electronic device 110 by a user 120 who desires to create a content file, electronic device 110 may gather information on or from other devices located in the vicinity of electronic device 110 to identify a context at the time of generating the content file. In the example embodiments described with reference to FIG. 1, electronic device 110 may gather information on or from devices 130 a, 130 b and 130 c in the vicinity of electronic device 110. By way of example, but not limitation, devices 130 a, 130 b and 130 c may be mobile devices controlled by other user or non-mobile devices including, for example, a base station of wireless local area network (LAN).

In some embodiments, content file creation event 100 may be triggered when user 120 captures a photo or a video with a camera (not shown) in electronic device 110, receives or downloads a file from any other devices, etc.

In some embodiments, electronic device 110 may identify the other devices located in the vicinity of electronic device 110 using at least one of Bluetooth, Wi-Fi and global positioning system (GPS). By way of example, but not limitation, in cases of using Wi-Fi, electronic device 110 may gather the information on or from devices located within Wi-Fi range (typically of a radius of about 100 ft (30 m) indoors or about 300 ft (90 m) outdoors), while in cases of using Bluetooth, electronic device 110 may gather the information on or from devices located within Bluetooth range (typically 32 ft (10 m) or less) from electronic device 110.

In some embodiments, the information on or from devices 130 a, 130 b and 130 c may be associated with identifiers of devices 130 a, 130 b and 130 c. By way of example, but not limitation, the information on or from devices 130 a, 130 b and 130 c may be media access control (MAC) addresses or service set identifiers (SSIDs) of devices 130 a, 130 b and 130 c.

In some embodiments, electronic device 110 may store in storage 150 the content file with the information on or from devices 130 a, 130 b and 130 c as metadata corresponding to the created content file. Storage 150 may be a component of electronic device 110 or a separate cloud-based storage.

Although FIG. 1 illustrates that electronic device 110 may gather the information on or from three devices 130 a, 130 b and 130 c in the vicinity of electronic device 110, one skilled in the art will appreciate that electronic device 110 may gather information on or from any number of devices in the vicinity of electronic device 110.

FIG. 2 schematically shows an illustrative example of an environment where an electronic device may create a content list, arranged in accordance with at least some embodiments described herein.

As depicted, when a content list creation event 200 is triggered in electronic device 110 by user 120 who desires browsing content files and/or creating a content list of the content files, electronic device 110 may gather information on or from other devices located in the vicinity of electronic device 110 to identify a context at the time of generating the content list. In the example embodiments described with reference to FIG. 2, electronic device 110 may gather information on or from devices 230 a, 230 b and 230 c located in the vicinity of electronic device 110 when content list creation event 200 is triggered. In some embodiments, content list creation event 200 may be triggered when user 120 activates a photo viewing application or a photo editing application, a video playing application or a video editor application, or a document editor or a document viewer, etc.

In some embodiments, electronic device 110 may identify the other devices located in the vicinity of electronic device 110 using at least one of Bluetooth, Wi-Fi and GPS. By way of example, but not limitation, in cases of using Wi-Fi, electronic device 110 may gather the information on or from devices located within the Wi-Fi range (typically of a radius of about 100 ft (30 in) indoors or about 300 ft (90 in) outdoors) from electronic device 110, while in cases of using Bluetooth, electronic device 110 may gather the information on or from devices located within the Bluetooth range (typically 32 ft (10 m) or less) from electronic device 110.

In some embodiments, the information on or from devices 230 a, 230 b and 230 c may be associated with identifiers of devices 230 a, 230 b and 230 c. By way of example, but not limitation, the information on or from devices 230 a, 230 b and 230 c may be MAC addresses or SSIDs of devices 230 a, 230 b and 230 c.

Then, in some embodiments, electronic device 110 may compare the context identified in response to content list creation event 200 with one or more contexts previously identified in response to one or more content file creation events 100 and stored in storage 150. In some embodiments, electronic device 110 may calculate one or more similarities between the information on or from the devices in the vicinity of electronic device 110 when content list creation event 200 is triggered (e.g., devices 230 a, 230 b and 230 c) and metadata corresponding to the one or more content files stored in storage 150. In some embodiments, electronic device 110 may calculate the similarities between the MAC addresses or SSIDs of devices in the vicinity of electronic device 110 at the time of detecting content list creation event 200 (e.g., devices 230 a, 230 b and 230 c) and MAC addresses or SSIDs of devices in the vicinity of electronic device 110 at the time of detecting content file creation events 100.

In some embodiments, electronic device 110 may calculate the similarities between the MAC addresses or SSIDs of the devices in the vicinity of electronic device 110 at the time of detecting content list creation event 200 (e.g., devices 230 a, 230 b and 230 c) and MAC addresses or SSIDs of the devices in the vicinity of electronic device 110 at the time of detecting content file creation events 100, using a set coverage ratio. In cases in which S_(i) denotes a set of MAC addresses or SSIDs of the devices in the vicinity of electronic device 110 at the time of creating or storing one of the content files, and R denotes a set of MAC addresses or SSIDs of the devices in the vicinity of electronic device 110 at the time of creating the content list, the set coverage ratio may be defined by an example Formula 1 as follows:

$\begin{matrix} \frac{{{S_{i}\bigcap R}} - {{R - S_{i}}}}{S_{i}} & \left\lbrack {{Formula}\mspace{14mu} 1} \right\rbrack \end{matrix}$

As such, the set coverage ratio may be calculated by subtracting the size of the difference set of R and S_(i) from the size of the intersection of S_(i) and R, and dividing the result by the size of S_(i). In some embodiments, the similarity between S_(i) and R may be associated with (e.g., be proportional to) the set coverage ratio.

In some embodiments, electronic device 110 may calculate the similarities between the MAC addresses or SSIDs of the devices in the vicinity of electronic device 110 at the time of detecting content list creation event 200 (e.g., devices 230 a, 230 b and 230 c) and MAC addresses or SSIDs of the devices in the vicinity of electronic device 110 at the time of detecting content file creation events 100, using an area of a cluster of the devices in the vicinity of electronic device 110 at the time of detecting content list creation event 200 (e.g., devices 230 a, 230 b and 230 c). In some embodiments, the area of the cluster of the devices may be calculated as an area of a polygon formed by locations of the devices, which may be detected by using GPS. For example, in cases in which {right arrow over (p)}_(k) denotes a location vector of the location of k^(th) device among n devices, the area of the polygon formed by the locations of the devices may be calculated by an example Formula 2 as follows:

$\begin{matrix} {{\frac{1}{2}{\overset{n}{\sum\limits_{k = 1}}{{\overset{\rightarrow}{p}}_{k} \times {\overset{\rightarrow}{p}}_{k + 1}}}},} & \left\lbrack {{Formula}\mspace{14mu} 2} \right\rbrack \end{matrix}$ where {right arrow over (p)}_(n+1)={right arrow over (p)}₁

In some embodiments, using the area of the cluster of the devices in the vicinity of electronic device 110 at the time of detecting content list creation event 200 (e.g., devices 230 a, 230 b and 230 c) calculated in accordance with Formula 2, electronic device 110 may calculate the similarities between the MAC addresses or SSIDs of the devices in the vicinity of electronic device 110 at the time of detecting content list creation event 200 (e.g., devices 230 a, 230 b and 230 c), and MAC addresses or SSIDs of the devices in the vicinity of electronic device 110 at the time of detecting content file creation events 100. Illustrative examples of content list creation using the similarities calculated based at least in part on the area of the cluster of the devices will be described below in more detail with reference to FIGS. 3(A)-(B).

In some embodiments, electronic device 110 may calculate the similarities between the MAC addresses or SSIDs of the devices in the vicinity of electronic device 110 at the time of detecting content list creation event 200 (e.g., devices 230 a, 230 b and 230 c) and MAC addresses or SSIDs of the devices in the vicinity of electronic device 110 at the time of detecting content file creation events 100, using distances between any two of the devices in the vicinity of electronic device 110 at the time of detecting content list creation event 200 (e.g., devices 230 a, 230 b and 230 c). In some embodiments, the distances among the devices may be calculated using intensity of at least one of a Wi-Fi signal and a Bluetooth signal.

In some embodiments, electronic device 110 may generate a content list 250 based at least in part on the calculated similarities. In some embodiments, electronic device 110 may list at least a part of the one or more content files stored in storage 150 in order of the similarities between the information on or from devices 230 a, 230 b and 230 c and metadata corresponding to the one or more content files. In some embodiments, electronic device 110 may make a list including thumbnails of at least a part of the one or more content files stored in storage 150.

Although FIG. 2 illustrates that electronic device 110 may gather the information on or from three devices 230 a, 230 b and 230 c in the vicinity of electronic device 110, one skilled in the art will appreciate that electronic device 110 may gather information on or from any number of devices in the vicinity of electronic device 110.

FIGS. 3(A)-(B) schematically show illustrative examples of content list creation, arranged in accordance with at least some embodiments described herein.

In the example embodiments described with reference to FIGS. 3(A)-(B), it is assumed that user 120 has stored multiple photos in a storage (e.g., storage 150), one of which was taken in the vicinity of three devices 310 a, 310 b and 310 c, and another of which was taken in the vicinity of two devices 310 a and 310 c. In FIGS. 3(A)-(B), Cluster (A, B, C) denotes a cluster consisting of devices 310 a, 310 b and 310 c, while Cluster (A, C) denotes a cluster consisting of devices 310 a and 310 c. In cases in which electronic device 110 determines that Cluster (A, B, C) is most similar to context at the time of creating a content list (e.g., a list of photos), electronic device 110 may list the photo taken in the vicinity of three devices 310 a, 310 b and 310 c at the top, while in cases in which electronic device 110 determines that Cluster (A, C) is most similar to the context at the time of creating the content list, electronic device 110 may list the photo taken in the vicinity of two devices 310 a and 310 c at the top.

As depicted in FIGS. 3(A)-(B), electronic device 110 may calculate an area and a purity of each cluster, and define the similarity as the purity divided by the area. In some embodiments, the areas of the clusters may be calculated using Formula 2 described above.

In the example embodiments illustrated in FIG. 3(A), the area of Cluster (A, B, C) may be same as the area of Cluster (A, C), but the purity of Cluster (A, B, C) may be higher than the purity of Cluster (A, C). In such cases, electronic device 110 may determine that the similarity for Cluster (A, B, C) may be higher than the similarity for Cluster (A, C), and thus list the photo taken in the vicinity of devices 310 a, 310 b and 310 c at the top.

In the example embodiments illustrated in FIG. 3(B), the purity of Cluster (A, B, C) may be the same as the purity of Cluster (A, C), but the area of Cluster (A, B, C) may be larger than the area of Cluster (A, C). In such cases, electronic device 110 may determine that the similarity for Cluster (A, C) may be higher than the similarity for Cluster (A, B, C), and thus list the photo taken in the vicinity of devices 310 a and 310 c at the top.

Although FIGS. 3(A)-(B) illustrate that electronic device 110 may calculate the similarities using the area of the cluster of the devices, one skilled in the art will appreciate that electronic device 110 may use the distances among the devices instead of the area of the cluster of the devices.

FIG. 4 shows a schematic block diagram illustrating an example architecture for providing a context-based content list generation scheme for an electronic device, arranged in accordance with at least some embodiments described herein.

As depicted, electronic device 110 may include a nearby device information gathering unit 410, a content ranking unit 420 and a content list presenting unit 430. Although illustrated as discrete components, various components may be divided into additional components, combined into fewer components, or eliminated altogether while being contemplated within the scope of the disclosed subject matter.

Nearby device information gathering unit 410 may be configured to obtain information regarding one or more nearby devices in the vicinity of electronic device 110. In some embodiments, nearby device information gathering unit 410 may obtain the information regarding the one or more nearby devices when at least one of a content file creation event (e.g., content file creation event 100) and a content list creation event (e.g., content list creation event 200) is triggered.

In some embodiments, nearby device information gathering unit 410 may obtain the information regarding the one or more nearby devices using at least one of Bluetooth, Wi-Fi and GPS. By way of example, but not limitation, the information regarding the nearby devices may be associated with identifiers of the nearby devices such as, for example, MAC addresses or SSIDs of the nearby devices.

Content ranking unit 420 may be configured to determine relevance of one or more content files stored in a storage (e.g., storage 150) based at least in part on the information regarding the one or more nearby devices which may be obtained by nearby device information gathering unit 410, when a content list creation event is triggered. In some embodiments, content ranking unit 420 may calculate one or more similarities between one or more metadata of the one or more content files previously stored in the storage and newly obtained information on or from one or more nearby devices when the content list creation event is triggered.

Content list presenting unit 430 may be configured to present a content list in order of the relevance which may be determined by content ranking unit 420, when the content list creation event is triggered. In some embodiments, content list presenting unit 430 may list at least a part of the one or more content files in order of the similarities calculated by content ranking unit 420.

In some embodiments, electronic device 110 may optionally include the storage. In some embodiments, the storage may store the one or more content files with the information regarding the nearby devices obtained by nearby device information gathering unit 410 in response to one or more content file creation events.

FIG. 5 shows an example flow diagram of a process of creating a content file for providing a context-based content list generation scheme for an electronic device, arranged in accordance with at least some embodiments described herein.

The method in FIG. 5 may be implemented in an electronic device (e.g., electronic device 110) including nearby device information gathering unit 410, content ranking unit 420 and content list presenting unit 430. An example process may include one or more operations, actions, or functions as illustrated by one or more blocks 500, 510 and/or 520. Although illustrated as discrete blocks, various blocks may be divided into additional blocks, combined into fewer blocks, or eliminated, depending on the desired implementation. Processing may begin at block 500.

At block 500, the electronic device may detect a content file creation event. In some embodiments, the content file creation event may be triggered when a user of the electronic device tries to create a content file, such as, for example, by capturing a photo or a video with a camera in the electronic device, or receiving or downloading a file from any other devices, etc. Processing may continue from block 500 to block 510.

At block 510, the electronic device may gather information on or from one or more nearby devices in the vicinity of the electronic device. By way of example, but not limitation, the nearby devices may be mobile devices controlled by other user or non-mobile devices including, for example, a base station of wireless local area network (LAN). In some embodiments, the electronic device may obtain the information on or from the nearby devices using at least one of Bluetooth, Wi-Fi and GPS. By way of example, but not limitation, the information may be associated with identifiers of the nearby devices such as, for example, MAC addresses or SSIDs of the nearby devices. Processing may continue from block 510 to block 520.

At block 520, the electronic device may store the content file with the information on or from the nearby devices as metadata corresponding to the created content file. The storage may be a component of the electronic device or a separate cloud-based storage.

FIG. 6 shows an example flow diagram of a process of creating a content list for providing a context-based content list generation scheme for an electronic device, arranged in accordance with at least some embodiments described herein.

The method in FIG. 6 may be implemented in an electronic device (e.g., electronic device 110) including nearby device information gathering unit 410, content ranking unit 420 and content list presenting unit 430. An example process may include one or more operations, actions, or functions as illustrated by one or more blocks 600, 610, 620 and/or 630. Although illustrated as discrete blocks, various blocks may be divided into additional blocks, combined into fewer blocks, or eliminated, depending on the desired implementation. Processing may begin at block 600.

At block 600, the electronic device may detect a content list creation event. In some embodiments, the content list creation event may be triggered when the user tries to browse the content files stored in a storage, such as, for example, by activating a photo viewing application, a photo editing application, a video playing application, a video editor application, a document editor or a document viewer, etc. Processing may continue from block 600 to block 610.

At block 610, the electronic device may gather information on or from one or more nearby devices in the vicinity of the electronic device. By way of example, but not limitation, the nearby devices may be mobile devices controlled by other user or non-mobile devices including, for example, a base station of wireless local area network (LAN). Processing may continue from block 610 to block 620.

At block 620, the electronic device may calculate one or more similarities between the information on or from the nearby devices and metadata corresponding to one or more content files stored in the storage. By way of example, but not limitation, the electronic device may calculate the similarities by calculating a set coverage ratio in accordance with Formula 1 above, or by calculating an area of a cluster of the one or more nearby devices, or by calculating distances between any two of the nearby devices. Processing may continue from block 620 to block 630.

At block 630, the electronic device may generate a content list based at least in part on the calculated one or more similarities. In some embodiments, the electronic device may list at least a part of the one or more content files in order of the calculated similarities.

The present disclosure is not to be limited in terms of the particular embodiments described in this application, which are intended as illustrations of various aspects. Many modifications and variations can be made without departing from its spirit and scope, as will be apparent to those skilled in the art. Functionally equivalent methods and apparatuses within the scope of the disclosure, in addition to those enumerated herein, will be apparent to those skilled in the art from the foregoing descriptions. Such modifications and variations are intended to fall within the scope of the appended claims. The present disclosure is to be limited only by the terms of the appended claims, along with the full scope of equivalents to which such claims are entitled. It is to be understood that this disclosure is not limited to particular methods, reagents, compounds, compositions or biological systems, which can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.

As will be understood by one skilled in the art, for any and all purposes, such as in terms of providing a written description, all ranges disclosed herein also encompass any and all possible subranges and combinations of subranges thereof. Any listed range can be easily recognized as sufficiently describing and enabling the same range being broken down into at least equal halves, thirds, quarters, fifths, tenths, etc. As a non-limiting example, each range discussed herein can be readily broken down into a lower third, middle third and upper third, etc. As will also be understood by one skilled in the art all language such as “up to,” “at least,” and the like include the number recited and refer to ranges which can be subsequently broken down into subranges as discussed above. Finally, as will be understood by one skilled in the art, a range includes each individual member. Thus, for example, a group having 1-3 cells refers to groups having 1, 2, or 3 cells. Similarly, a group having 1-5 cells refers to groups having 1, 2, 3, 4, or 5 cells, and so forth.

From the foregoing, it will be appreciated that various embodiments of the present disclosure have been described herein for purposes of illustration, and that various modifications may be made without departing from the scope and spirit of the present disclosure.
